Limitations in current day lighting related solar concentration devices: A critical review

      This study introduces the day lighting related solar concentration devices such as light pipes (or tubular daylight guidance systems), optical fibers for light transport, conventional solar concentrators and luminescent solar concentrators (LSC). The principles of study, advantages and disadvantages for application of these day lighting related devices have been explained. Daylight has a...

Anti-synchronization of Liénard chaotic systems via feedback control

Based on the Lyapunov stability theory, this paper presents the feedback controllers for anti-synchronizing Liénard systems. A sufficient condition is drawn for the robust stability of the error dynamics and the design of the controllers. Numerical simulations are performed to verify and illustrate the analytical results.   Key words: Anti-synchronization, Liénard system, feedback...
